Can't Assign Value

First of all, bear with me. Only on my 3rd week of java programming, so stupid error will occuor

Lets start with the code in question:

Code:

public Matrix multiplyMatrix(Matrix B)    {        if(coln != B.returnRowlength())        {        Matrix local = new Matrix(rows, B.returnColnlength());        int value = 0;            for(int i = 0; i < rows; i++) // Controls row count            {                for(int j = 0; j < B.returnColnlength(); j++) // Control coln count                {                    for(int k = 0; k < coln; k++)                    {                        value = value + (array[i][k] * B.returnValue(k,j));                     local[i][j] = value;                    }                }            }            return local;        }        else        {              System.out.print("Dimension does not match. Multiplay function cannot be executed.");        }    }

I get this error message: array required, But matrix found

local is an array, so why does it say array required?

Thanks,kvarnerexpress

APCS in Java? I'm in that class, too... and we just got that problem today. I haven't finished it but basically your problem is that local is an object, not an array. Arrays are special, so they can be accessed using []'s, but objects can't. What I did for that part was to make local a two dimensional array (int[][] local = new int[number of rows in a][number of cols in b]) and a constructor for the Matrix class that took a two dimensional array argument:

int[][] data;public Matrix(int[][] a){   data = a;}
